[Abstract]:In the aspects of high efficiency heat dissipation design of insulated gate bipolar transistor (IGBT) module and long-term reliability evaluation of converter system, it is usually necessary to know the temperature of IGBT module. However, the simulation of the existing models and methods is time-consuming, so it is difficult to quickly solve the temperature of IGBT module. In order to solve this problem, the idea of direct method is used for reference in this paper. In this paper, a new fast algorithm for calculating the temperature of IGBT module is proposed. Based on the fitting and interpolation algorithm, the power loss model of IGBT module is derived and established. Based on the theory of electrothermal analogy, the equivalent Cauer heat transfer network model of IGBT module with concentrated parameters is discussed and established, and the differential heat transfer differential equation is differentiated. Finally, a fast algorithm for calculating the temperature of IGBT module is constructed in the same circuit simulator. In the example of two-level three-phase inverter, the temperature calculation results of Infineon IPOSIM are compared with those of Infineon IPOSIM. The results show that the maximum error of the algorithm is 3.01, and the trend of temperature variation is basically consistent with that of IPOSIM. Compared with the traditional physical model based on IGBT and the calculation time of the thermal network component model, it shows that the computational speed of the proposed algorithm is nearly 1 255 times higher than that of the traditional physical model based on IGBT.
